Clutch having elements capable of independent operation

摘要

A freewheeling clutch includes torque transmitting elements disposed between an inner race and an outer race. The elements include active surfaces that may be defined by an angularly variable radius of curvature that varies with respect to roll angle at an increasing rate, such as an equiangular spiral, to form a constant strut angle as the elements move between a freewheeling and an engaged position.
